I had it randomly as well after I started high school. I always could say my name perfectly, but bam, on the first day it's been hard ever since. I'm 3 years deep in high school now, and one of the strategies I've used is saying something like "you got 3 guesses" and then while they're guessing ill work out saying it lmao. This might only work at school tho, as a certain amount of decorum is needed in a workplace...
